GANG EDGlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 484,431, dated October 18, 1892.

Application filed February 7, 1890. Serial No. 339,577- (No model.)

To all whom it may concern.-

Be it known that we, EDWARD HoLMEs and BRITAIN HoLMEs, citizens of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Gang Edging-Machines, of which the following is a specification.

Our invention consists in certain improvements in gang edging-machines, and will be fully and clearly hereinafter described and claimed, reference being had to the accompanying drawings, in which Figure 1 is aside elevation of a gang edgingmachine, showing as much of the machine as 1s necessary to properly illustrate our inventlon. Fig. 2 is a reverse side elevation of a portion of the machine, showing a similar view of the feeding mechanism for adjustlng the speed of the feed-rolls, so as to adapt the speed of the feeding mechanism for different thicknesses and different kinds of material to be sawed. Fig. 3 is a top plan View of a gang-edger, showing a similar view of our invention connected therewith, some well-known portions of the machine being omitted so as to more clearly show what is new. Fig. 4 is a detached side elevation of the feed mechanism. Fig. 5 is a sectional elevation cutting through line a b, Fig. 4.

In the drawings, 1 and 2 represent the two iron frame-pieces of a gang-edger. At each side is the usual extension wooden frame 3. A gang of saws 4 and 4* are mounted on the driving-shaft 5, on which is secured, bya key pr other well known means, the driving-pul- 7 represents a tightening-pulley mounted on a pivoted lever S for keeping the feed-motion belt 9 taut. This belt 9 runs on feedpulleys 10 and 11, mounted on shafts 12 and 13, set in suitable bearings e on the frame of the machine.

The numerals 12, 13, and 14 represent the feed-rolls over which the material to be sawed passes into and out of the machine; but as all these parts and certain other portions of the machine are well known a further description of them here is not required.

15 is a thin metallic dividing guide-bar which separates the portion sawed from the board. It also acts as a gage to keep the board in line.

The adjustable portion of the feed device consists of the two feed-disks 11 and 16. They receive their motion by means of the small pulley 17 on the driving-shaft and the larger pulley 18, mounted on a shaft 19 below it. The shaft 19 turns in bearings, and on its outer end is the feed-disk 16. The pulleys 17 and 18 are connected by a belt 20. (Shown in Fig. 2.) i

To the horizontal frame-bar 21 (shown in Fig. 2) is rigidly secured in any well-known way an outwardly-projecting arm 22. (See Figs. 3, 4, and 5, Where portions of this arm are shown, a section through it being shown in Fig. 4.) To the arm 22 is rigidly secured a cross-bar 23. Both the arm 22 and bar 23 are stationary, the supporting-arm 22 being rigid- 1y fastened in any suitable way to the framebar 21. This frame-bar 21 is shown in Fig. 2, and the arm 22 projects upward and out from it and is shown below the Wheels 10 and 11 in Fig. 3, and portions of it also in the other figures, as above mentioned.

Upon the cross-bar 23 is mounted a framepiece 24, adapted to slide back and forth easily on said bar, but is prevented from turning thereon by means of a feather 25, (shown in Figs. 4 and 5,) or in any Well-known way. The frame-piece 24 is provided with journals 25, in which is mounted a shaft 26, carrying the two friction-wheels 27. The construction is such that the friction-wheels 27 bear with sufficient force-one on the disk 11 and the other on the face of the disk 16to give all the frictional contact that may be required to run the feeding mechanism and are located on the machine substantially as shown in Fig. 2.

To the frame-bar 21 is rigidly secured an outwardly-projecting arm 28, (see Figs. 2 and 3,) t0 the outer end of which is pivoted a handlever 29, so as to turn easily thereon. Ashort arm 30 projects from the lever 29 (see Figs. 2 and 3) and is provided with a slot 31, which passes over the pin 32. (See Fig. 2.) From this construction it will be seen that a movement of the hand-lever 29 can be made to cause the friction-Wheels 27 to move toward the center of the disk 11 and away from the center of the disk 16, or vice versa, and thus nected to the guide-bar 33 by a short connecting-rod 38, pivoted thereto and to the guidebar by pins 39 and 40. (See Fig. 3.) In some cases (smaller machines, for instance) the hand-lever 36 may be dispensed with and the guide-bar may be given its required lateral movement by band. From this construction it will be seen that a movement of thehandlever 36 in the direction of the arrow 1) (see Fig. 3) will cause the guide-bar 33 to move longitudinally in the same direction, and'at the same time laterally in the direction, of the arrow f, or toward the board 42, which requires to be straightened at the edge next to the guide-bar, and that a reverse movement of the hand-lever will cause several parts tobe moved in the opposite direction, or in the direction of the arrows fand 1;, so that a board may be quickly and easily brought into such a position that its narrowest portion will be in a line with the saw 4, and so that only enough will be taken off to straighten the board, or the necessary movements may be given to the guide-bar 33, as before mentioned, and, if desired, the feed gage-bar, the slot being long enough to allow for the curved movement of the hand-lever. We claim as ourinventron- In a gang edging-machine, the combination therewith of thefeed-rollers forfeeding the material into the machine, two disks 11 and16, two friction-rollersadaptedto roll byfrictionalcontact on each disk and secured at opposite ends of a shaft mountedso as to turn in journals in a supporting-frame, a stationary bar or slideway secured to the frame of the machine and upon which the holdingframe is supported,so as to slidelongitudinally back and forth thereon and cause the friction-rollers to bear against the faces of thedisks, a handlever pivoted to the frame of the machine and to the sliding supporting-frame for moving the friction-rollers to or from the center of each disk, and thereby adjusting the speed of the feed motion, and a means for giving the disk 16 a rotary motion, substantially as described.
